GLib.Error: udisks-error-quark: GDBus.Error:org.freedesktop.UDisks2.Error.Failed: Error setting partition flags on /dev/sdb2: Command-line `parted --script "/dev/sdb" "set 2 boot off"' exited with non-zero exit status 1: Error: The backup GPT table is not at the end of the disk, as it should be. Fix, by moving the backup to the end (and removing the old backup)?
Warning: Not all of the space available to /dev/sdb appears to be used, you can fix the GPT to use all of the space (an extra 31250608 blocks) or continue with the current setting?
Error: Can't have overlapping partitions.
